In the world of sophisticated sound systems, the Ferrum Audio OOR Analogue Headphone Amplifier stands as a paragon of innovation and quality, a testament to Ferrum’s commitment to pure, unadulterated sound reproduction. This state-of-the-art device has not only been honored as the best Headphone Amplifier for 2022-2023 by the esteemed EISA members but has also set a new standard in the category of headphone amplifiers.

The OOR Amplifier, with its full-balanced analog signal path, is a product of Ferrum’s proprietary technology. It features a unique discrete power amp design that is the bedrock of its ability to deliver sound with ultra-low distortion, expansive dynamics, and unparalleled detail. What sets OOR apart is its ability to pair seamlessly with the HYPSOS Hybrid Power System, via the Ferrum Power Link (FPL), designed to unlock new echelons of musicality from the headphones it powers.

The essence of OOR’s design philosophy is evident in every aspect of its performance. With a truly balanced approach, it ensures that the audio signal remains balanced whether through XLR inputs or RCA inputs, providing a consistently pure and transparent sound signature. This balanced design contributes to a listening experience devoid of fatigue, allowing for extended periods of immersive enjoyment.

Furthermore, Ferrum’s dedication to excellence is embodied in the OOR’s ease of use. The amplifier boasts a front panel with just three knobs, a design choice that grants users intuitive control over the most crucial settings. This simplicity, however, belies the sophisticated technology within.

The control exhibited by the OOR amplifier is nothing short of superior. Its innovative steering of output transistors ensures they remain in an optimal state, poised to deliver power instantaneously. This is essential for maintaining high dynamics, control, and authoritative sound quality. The discrete power amp technology, developed in-house, underscores Ferrum’s commitment to exceptional analog sound quality.

An aspect of the OOR amplifier that deserves special mention is its unique output cable design. The Ferrum Power Link technique uses two wires for power delivery and two wires for feedback, which guarantees a constant voltage at all times. This innovation greatly reduces the detrimental effects of cable resistance and significantly improves the transient response, thereby enhancing the current delivery speed at the input of the powered device.

The OOR comes with a meticulously chosen DC power adapter. However, for those wishing to explore the full potential of this remarkable amplifier, connecting it to the HYPSOS via the proprietary Ferrum Power Link DC power cable—which is available for separate purchase—is recommended. This connection unleashes an even greater level of performance from the OOR, taking the listening experience to heights previously unheard.
